Our national parks are almost all we have left, at least here in the US. Without conservancy laws and regulations we woulsnt even have those left. I worry for the future. What will happen when there is no where else to build? Will those laws be lifted? Our oceans are being contaminated at every border by humans all over. All the trash we compile goes to a wasteland and builds up from there. We treat our earth like garbage, not realizing this is our only home. Conservation methods are what we all need. Reuse and recycle. Take care of your planet.
