Give 6 ways that society has tried to reduce the negative effects of humans on the environment and maintain biodiversity.

  1. Breeding programmes for endangered species.
  2. Protection and regeneration of rare habitats.

  4. Rules for reduction of deforestation by government.
  5. Rules for reduction of carbon dioxide emissions by government.
  6. Recycling resources rather than dumping waste in landfill.

How do field margins and hedgerows in agriculture help increase biodiversity? 

They provide extra habitats and food sources so that a wider range of species can survive. This is particularly important if only one type of crop is being grown in the fields.

How can breeding programs be used to improve biodiversity? 

Endangered species can be bred in captivity where they're safe. Once they're old enough, individuals can be released into their natural habitat to increase biodiversity.

Suggest 3 limitations of breeding programs.

1Some species are difficult to breed in captivity.


2Some species can't survive by themselves after being raised in a breeding program.


3There may not be enough natural habitat for the species to be reintroduced to.

Suggest 3 ways government might limit the carbon dioxide produced by companies?

1They could create a 'carbon tax', in which companies have to pay for each ton of carbon dioxide that they emit.


2They could create quota or limits on the maximum amount of carbon dioxide companies can emit.


3They could create laws to ban certain practises that release a lot of carbon dioxide.
