Plastic bottles become a greenhouse

Plastic bottles become a greenhousePosted by Rique

I usually go for projects that are way more imprecise than building a greenhouse out of plastic bottles. But it seems pretty simple. There are all sorts of free plans online. What a great project for teachers. The kids can collect the bottles and along the way learn about recycling and how many bottles end up in landfills each year. (Over 35 billion) They can get their hands dirty and also learn biology. Pretty amazing what you can do with stuff that people throw away.

A few facts I got from Earth911.com:
Americans buy an estimated 29.8 billion plastic water bottles every year.
Nearly eight out of every 10 bottles will end up in a landfill.
It is estimated that the production of plastics accounts for 4 percent of the energy consumption in the U.S.
Less than 1 percent of all plastics is recycled. Therefore, almost all plastics are incinerated or end up in a landfill.
Recycling a single plastic bottle can conserve enough energy to light a 60-watt light bulb for up to six hours.
