why do we have to protect the environment at all
The Earth systems are under threat. Global warming, freshwater depletion, biodiversity reduction, hole in the ozone layer - are all examples of such threats. One has to ask oneself what can be done to stop this development. How serious is it really? And what is it actually possible to do to change the direction? Even though much of what is happening in the world today does not show it, we are totally dependent on the natural environment. Just because we as humans have the power to destroy environment and other species, this does not give us any right to do so.
But more convincing to the ones having power in today's world is probably the economic argument. That we cannot afford to destroy the Earth systems. Attempts have been made to estimate the value of the services our environment give. This added up to 33 trillion USD (33 million millions) every year. This amount is nearly the double of the total world economy. The value of nature's flood and storm protection is calculated at 1. 1 trillion, and water and climate regulation at 4. 1 trillion USD. The value of the services provided by coral reefs is estimated at 375 billion $/year.
But these coral reefs are destroyed at an alarming rate. In 1992 10 % had permanently been destroyed and this grew to 27 % in 2002.
3. The problems with chemical Other farming practices can impact the climate. Pesticides and fertilizers are widely used in farming, and are often made from fossil fuels. Manufacturing and transporting these chemicals uses some amounts of energy and produces. Studies have shown that chemical farming uses more energy than organic farms, which do not use these chemicals.
In addition, the use of nitrogen fertilizers in soils produces nitrous oxide, a greenhouse gas that is approximately 300 times more powerful than carbon dioxide at trapping heat in the atmosphere. Organic farms, on the other hand which rely on natural manure and compost for fertilizer store muck more carbon in the soil, keeping it out of the atmosphere. Where your food comes from is also important. Currently, the average meal travels 1200 km from the farm to plate.
Food that is grown closer to home will have fewer transportation emissions and also be fresher and support local farmers. And as the distance food travels decreases, so does the need for processing and refrigeration to reduce spoiling the food. Choosing to buy food that is organically grown can therefore be a better choice for the climate. But if possible, buy food that that is organic and local. Ways to help stop pollution! 1. Reduce, Reuse, Recycle Do your part to reduce waste by choosing reusable products instead of disposables.
Buying products with minimal packaging (including the economy size when that makes sense for you) will help to reduce waste. And whenever you can, recycle, newspaper, glass and aluminum cans. If there isn't a at your workplace, school, or in your community, ask about starting one. By recycling half of your household waste, you can save 2,400 pounds of carbon dioxide annually. 2. Walk and save money! Walk to school instead of driving in a car! this will save money,fuel,and pumps less carbon dioxide in the air.
