Although some geophysical scientists think the Earth is about 4.7 billion years old, when do you think the first Earth Day was celebrated in the United States?If you guessed right in more than 50 years, then you are wrong.April 22, 1970 is recognized as the first Earth Day.This is not a celebration at all;The opposite is true.Senator Gaylord Nelson from Wisconsin, known as the "father of the Earth", used the idea as an environmental protest designed to shake political institutions and put the issue on the national agenda.More than 20 million people took to the streets to support the protests that day.In fact, the establishment of the Environmental Protection Agency is a direct result of the first Earth Day.Now, almost 40 years later, environmental awareness seems to be rising again, and Earth Day is more of a celebration than a protest.So what are the relatively easy things you do today and in the future to help the environment?1.First of all, you should recycle.The ink cartridge is a killer.The same is true of most electronic products.Don't throw away your old phone, printer, computer, glass, battery, newspaper, plastic with #1 or #2 printed on the bottom, Solicitation mail (aka spam), cereal and shoe box.They should all be recycled.2.Reuse bags.Bring the bag back to the grocery store and refill it with new groceries.It's better to bring a canvassing bag.3.4.Unplug the charger (phone, computer, etc ).) And turn off lights and other electronic devices when not in use.5.Use organic and natural landscape techniques.No pesticides are needed to produce green lawns.6.A programmable thermostat is installed.Whether it's up or down, not only does each degree consume less energy, but it's also better in your wallet.7.Less water: do not run water when brushing your teeth and take less shower time.8.Use water bottles that can be refilled.Those small plastic water bottles are a killer to the environment.9.Download e-books.No trees were hurt and no ink was used to create digital books.Better yet, download digital books about the environment.Here is one for the children: all the way to the ocean.10.Use a bus, subway, bike or walk if possible.1.The average income of Americans is more than 3.5 pounds of garbage a day2.When lighting with a standard bulb, about 90% of the energy is lost with heat.3.Plastic bags and other plastic waste thrown into the ocean kill up to 1 million marine creatures every year.4.S. industry releases 4 billion pounds of toxic pollution every year.5.About 1 billion books are buried each year.Let's spend some time celebrating the earth in April 22.You will be very happy.In the coming centuries, so will the generations who will walk on this earth.
