Why might a tyre manufacturer choose to use synthetic rubber instead of natural rubber?
Synthetic rubber is easier to make and its properties can be better controlled.
Which method of extraction uses organisms that absorb metal compounds?
phytomining and bioleaching
What type of development meets the needs of current generations without compromising the ability of future generations to meet their own needs?
sustainable development
Wheat farmers can increase the amount of wheat they grow by using genetically modified crops and by controlling the growing conditions. In this example, is agriculture being used to replace or supplement natural products?
supplement natural products
What metal is often extracted and purified from its ore using both smelting and electrolysis?
