Challenges of Maintaining Biodiversity Flashcards

1️⃣ Familiarise yourself with the flashcards:

Look through all the flashcards to see what's on both sides.
Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

Look at the question or prompt on each card and try to remember the answer before flipping it over.
Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

Why can building new houses and roads be a challenge for maintaining biodiversity?

They often destroy or break up habitats, so fewer species can live and breed there.

There is not enough money to protect every species and habitat, so only some can be helped.

People may need land, wood or jobs, so they may not agree to strict nature reserves or hunting bans.

It changes temperature and rainfall, so some species cannot adapt or move in time and may die out.

There are often only a few animals, so inbreeding can reduce genetic variation and make them less healthy.

They may not know how to find food or avoid predators, and there may not be enough safe habitat for them.

Seeds must be kept cold and dry and tested often, which costs money and energy, and some seeds do not store well.

Many species cross borders, so countries must agree on rules, but it is hard to make every country follow them.

We may not notice a species is in danger until its numbers are very low, so it is harder to save in time.

Illegal hunting or collecting can quickly reduce numbers of rare species, even when laws are meant to protect them.
