BARSIC [14]

Answer:

alright bet I got this

Explanation:

Have you ever wondered what can happen to those plastic bottles you toss away? How do they decompose? What happens to them? Its simple really, they get eaten! No, not by people of course they are eaten by a tiny critter called a wax worm. The wax worms earn their name because they are often found living in beehives where they eat the beeswax.

Wax worms much like mealworms are used to break down things that would normally be endangering to our environment. These seemingly useless little animals do a whole lot for our environment especially with the amount of waste we produce! They really are a tiny secret hero to todays pollution problem.

After quite a few studies scientists are still unsure on how was worms can breakdown plastic with their tiny bodies but they appreciate the work these little recyclers do. They have a lot of theories on how these worms do this one of the theories is that bacteria can break it down, another theory is that enzymes in the worms intestines break down plastics. Though scientists believe it will take a while to figure this out they enjoy studying and learning more about this tiny helper.

How did creating a greenbelt affect sprawl? Why do you think this happened?
scZoUnD [109]
The OECD found that the responsiveness of housing supply to demand in the UK was the weakest among developed countries, due in large part to green belt policies. The green belt concept was first introduced for London in 1938 before the 1947 Town and Country Planning Act enabled local authorities to designate the status themselves. The policy was introduced to contain urban sprawl following huge post-war housing developments, and expanded greatly between 1951 and 1964. Since 1979, the green belt has doubled to cover 13 per cent of land in England (while only 2.3 per cent is covered by buildings).
