Human Extinction Has Began
We are slowly killing ourselves and our planet without even knowing it. We are burning non renewable resources such as coal, gas, and oil for our energy needs. China for example has a very high pollution rate. The pollution is so bad that they cannot see the sun because of the smog. There have been reports of finding chemicals in Polar Bears in the Antarctic having chemicals in their bodies when they are nowhere around humans or chemical use. We are unaware that our actions have consequences. Think about this for second: we spray our lawns with chemicals, we then water our gardens or grass, the water run off gets drained into the water drain in the ground, then it flows into the lake or ocean (which ever is your run off system in your city), our fish swim around in that water, birds eat the fish and migrate all over, then the kicker-when it starts to rain, where do you think the water comes from? That's right. The ground, oceans, lakes, etc. If we pollute one thing, it all gets polluted. I am not some big environmental advocate by any means. I am simply a person trying to get people to understand how our actions have consequences for us and other species.
5 Human Impacts on the Environment: Crash Course Ecology
Greenhouse Effect is the heating up of our atmosphere when the Sun's radiation passes through the atmosphere and is absorbed by earth and is given off as long wavelength of radiation that is absorbed by atmospheric gases such as Carbon Dioxide and water vapor. This has been changing rapidly since the start of the Industrial Revolution. We are rapidly ripping down trees and not replacing them, making thousands of species extinct by killing them off, burning fossil fuels, and so much more. We keep using fossil fuels hoping that they will not run out. Well guess what? They are running out and quickly.
About two thousand years ago there were around 300 million people on earth. in the early 1800s there was around one billion people on earth. Today there are over seven billion people alive. Each year our human race population increase about 70 to 80 million each year. Those numbers are surprising to me. We are damaging our earth and we are leaving the mess for the next guy. We have access to Renewable resources for our electric needs. They are wind power, solar panels, electric cars, water power, all natural products for outdoor and indoor use, etc. If we all plant a garden and a tree that would mean that there would be 70 billion new trees. 70 billion gardens producing fruits, vegetables, flowers, etc. If we all help clean up, we will have a better planet for the future generations.
