Mother Nature is an unrelenting, unforgiving force so it is the best if we treat her well because all of it will go back to us, the effect and the use of the Nature around us. The best time to act was yesterday, the best we can do is today, but if we wait for tomorrow it may just be too late. Our Earth is a very beautiful planet. Among all the planets in the universe, the Earth is the loveliest, with mountains, oceans, and all manner of environments, each a home to many kinds of creatures. Mother Earth sustains all life on it, including us humans. She provides all the food we eat and the material goods we use. But her health is declining and she's losing her ability to protect and provide for the creatures living on the land. Natural disasters, such as floods, mudslides, wildfires, drought, and earthquakes, cause damage to the Earth. Crops are destroyed as a result of drought or flooding, leading to food shortages and famine. People lose their lives and their homes as a resu...

Desist from using pesticides Pesticides are great chemicals to rid your farm of pests and weeds, but they contribute enormously to ozone layer depletion. The surefire solution to get rid of pests and weeds is to apply natural methods. Just weed your farm manually and use alternative eco-friendly chemicals to alleviate pests. Discourage driving of private vehicles The easiest technique to minimize ozone depletion is to limit the number of vehicles on the road. These vehicles emit a lot of greenhouse gases that eventually form smog, a catalyst in the depletion of ozone layer. Utilize environmentally friendly cleaning products Most household cleaning products are loaded with harsh chemicals that find way to the atmosphere, eventually contributing to degradation of the ozone layer. Use natural and environmentally friendly cleaning products to arrest this situation. Prohibit the use of harmful nitrous oxide The Montreal Protocol formed in 1989 helped a lot in the limita...

The earth’s atmosphere is composed of many layers, each playing a significant role. The first layer stretching approximately 10 kilometers upwards from the earth’s surface is known as the troposphere. A lot of human activities such as gas balloons, mountain climbing, and small aircraft flights take place within this region. The stratosphere is the next layer above the troposphere stretching approximately 15 to 60 kilometers. The ozone layer sits in the lower region of the stratosphere from about 20-30 kilometers above the surface of the earth. The thickness of the ozone layer is about 3 to 5 mm, but it pretty much fluctuates depending on the season and geography. Ozone layer is a deep layer in earth’s atmosphere that contain ozone which is a naturally occurring molecule containing three oxygen atoms. These ozone molecules form a gaseous layer in the Earth’s upper atmosphere called stratosphere. This lower region of stratosphere containing relatively higher concentration of ozon...

MAN by STEVE CUTTS This video conveys a perspective that has many supporters and touches on some key prevalent conceptions of humans’ relationship to nature. Ceaseless searching for the values that are to shape a new way of being and doing, one that is desperately needed for humanity to evolve towards its maturity, should not be done in isolation. To offer alternatives to the current modus operandi, we must be well informed of current attitudes and beliefs, and we must be ready to face different perspectives. Indeed, very often we come up against statements that belittle our vision and dismiss it as purely idealistic. This means that it is of the utmost importance to develop the capacity to articulate ideas that legitimize a position that rises above the materialistic thinking widespread in today’s society.

Reduce Emissions In order to effectively address global warming, we must significantly reduce the amount of heat-trapping emissions we are putting into the atmosphere. As individuals, we can help by taking action to reduce our personal carbon emissions. But to fully address the threat of global warming, we must demand action from our elected leaders to support and implement a comprehensive set of climate solutions. Stop Deforestation Tropical deforestation accounts for about 10 percent of the world’s heat-trapping emissions — equivalent to the annual tailpipe emissions of 600 million average U.S. cars. Reducing tropical deforestation can significantly lower global warming emissions and — together with efforts to reduce emissions from fossil fuels — plays an integral role in a comprehensive long-term solution to global warming. Fight Misinformation Why has it been so difficult to achieve meaningful solutions to global warming? Media pundits, partisan think tanks, and...

Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. And experts see the trend is accelerating: All but one of the 16 hottest years in NASA’s 134-year record have occurred since 2000. Climate change deniers have argued that there has been a “pause” or a “slowdown” in rising global temperatures, but several recent studies, including a 2015 paper published in the journal Science, have disproved this claim. And scientists say that unless we curb global-warming emissions, average U.S. temperatures could increase by up to 10 degrees Fahrenheit over the next century. Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gasses collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface. Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet ...

One of WWF’s two main approaches for preserving the world’s biodiversity is the 2050 Footprint Goal, an aim that by 2050 humanity’s global footprint will stay within the planet’s capacity to sustain life and that natural resources will be shared equitably. WWF has identified 100 companies that most directly impact the species and places that the organization is trying to protect. By engaging with these companies, WWF works to reduce the environmental impact of these businesses and champion sustainable solutions. ADVOCATING TO REDUCE POLLUTION Pollution is regulated at local, national and international levels. WWF works at all three levels to push for measures that will minimize the impacts of development and reduce pollution. INSPIRING LOCAL CONSERVATION WWF works to encourage local conservation and environmental awareness. For example, in June 2012 WWF helped organize the first Coral Triangle Day, to bring to light the importance of the oceans and the need to protect them....

Pollution, also called environmental pollution, the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The major kinds of pollution are (classified by environment) air pollution, water pollution, and land pollution. Modern society is also concerned about specific types of pollutants, such as noise pollution, light pollution, and even plastic pollution. Although environmental pollution can be caused by natural events such as forest fires and active volcanoes, use of the word pollution generally implies that the contaminants have an anthropogenic source—that is, a source created by human activities. Pollution has accompanied humankind ever since groups of people first congregated and remained for a long time in any one place. Indeed, ancient human settlements are frequently recognized by their poll...

Better Education One of the first measures is to implement policies reflecting social change. Educating the masses helps them understand the need to have one or two children at the most. Similarly, education plays a vital role in understanding latest technologies like CloudDesktopOnline that are making huge waves in the world of computing. Families that are facing a hard life and choose to have four or five children should be discouraged. Family planning and efficient birth control can help in women making their own reproductive choices. Open dialogue on abortion and voluntary sterilization should be seen when talking about overpopulation. Making People Aware of Family Planning As population of this world is growing at a rapid pace, raising awareness among people regarding family planning and letting them know about serious after effects of overpopulation can help curb population growth. One of the best way is to let them know about various safe sex techniques and contracepti...

Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation. It is possible for a sparsely populated area to become densely populated if it is not able to sustain life. Causes of Overpopulation Decline in the Death Rate: At the root of overpopulation is the difference between the overall birth rate and death rate in populations. If the number of children born each year equals the number of adults that die, then the population will stabilize. Talking about overpopulation shows that while there are many factors that can increase the death rate for short periods of time, the ones that increase the birth rate do so over a long period of time. The discovery of agriculture by our ancestors was one factor that provided them with the ab...

The Earth might seem solid beneath our feet but five billion years ago there was no sign of the planet we call home. Instead there was only a new star and a cloud of dust in our solar system. Over millions of years, a series of violent changes led to the formation of our world and, eventually, the creation of life. In this photorealistic CGI epic, see how a boiling ball of rock transformed into the blue planet we know today. Explore every aspect of our world; learn how water first arrived on Earth, discover the vital role oxygen played as life forms began to evolve, and find out how land mammals evolved into dinosaurs and other giant beasts, before becoming extinct 65 million years ago. Cutting-edge imagery also reveals how humans first began to walk on two feet and looks into the future to see what may be in store for our home over the next five billion years.

Since the earliest times, humans have needed to be sensitive to their surroundings to survive, which means that we have an innate awareness of our environment and seek out environments with certain qualities. First of all, humans have a strong need for safety and security and look for those attributes in their environment. We also look for physical comfort, such as an environment with the right temperature. In addition, we seek an environment that is psychologically comfortable: for example, environments that are familiar, but offer the right amount of stimulus. Think about health stuff first—bad air quality can give us respiratory problems, polluted water can make us sick, and we need sunlight to live (it regulates our internal clocks, it helps us produce vitamin D in our skin) but too much of it can burn us, or even cause us to develop skin cancer. Stuff like that. Or consider how the environment affects the way we live. People have figured out ways of dealing with extreme heat...

HUMAN SOCIAL SYSTEM The flow and use of critical resources is regulated by the social system, the set of general social structures that guide much of human behavior. The social system is composed of three subsystems: social institutions, social cycles, and social order. Taken together, social institutions, combined with the flow of critical resources, create the human ecosystem. Each of these elements substantially influences the others. For example, changes in the flow of energy (such as an embargo and resultant rationing) may alter hierarchies of power (those with fuel get more) and norms for behavior (such as informal sanctions against wasting fuel). Adaptation is continuous in human ecosystems (Bennett 1976); social institutions adapt to changes in resource flows, and in turn, alter such flows. The result is a perpetually dynamic system. For example, political institutions may adapt to the increased demands on forest resources by altering decision-making processes (such as in...

Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface. Our atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe. The atmosphere also protects us from incoming meteoroids, most of which break up in our atmosphere before they can strike the surface as meteorites. Since we live here, you might think we know all there is to know about Earth. Not at all, actually! We have a lot we can learn about our home planet. Right now, there are many satellites orbiting Earth taking pictures and measurements. This is how we can learn more about weather, oceans, soil, climate change, and many other important topics. Earth is home to millions of species. Just one dominates it. Us. Our cleverness, our inventiveness and our activities have modified almost every part of our planet. In fact, we ...
