Some renewable technologies harness the vast mechanical power available from a planet that is in constant motion. Wave power generators (WPGs) are a possible energy source of the future, but how do they compare with their rivals?
All ecosystems are fragile and vulnerable to devastating chain reactions. By reducing the diversity of the plants on your lawn, you greatly reduce the hospitability of that environment for insects like bees, beetles and butterflies. This, in turn, has an effect on the food supply available to birds and small mammals. On top of all this, most of us cut the grass with either petrol-powered or electric mowers, both of which hasten and intensify climate change, the greatest threat currently facing people and animals alike.
