1. IDEA 1 OF 8

   We can build a sustainable world

   Ritchie, a data scientist, argues that despite real environmental problems, humanity could become the first generation to achieve a sustainable world.

   She uses data to challenge doom-filled thinking. She presents this as a hopeful but realistic claim.

2. IDEA 2 OF 8

   Data shows progress

   Ritchie argues that many indicators of human well-being, such as child mortality, have improved.

   Progress is possible. In her account, looking at long-term trends can show gains that daily news about bad events tends to hide, which supports a more balanced view.

3. IDEA 3 OF 8

   Air pollution can be tackled

   Ritchie explains that air pollution has fallen in many countries and can be reduced further.

   In her account, the fall shows that clear rules and cleaner technology can work, and that the same approach can help places where air is still badly polluted.

4. IDEA 4 OF 8

   Climate change is solvable

   Ritchie argues that clean energy is becoming cheaper, making climate solutions more achievable.

   In her account, cheaper solar, wind and batteries make it easier for countries to cut emissions, and costs have fallen faster than many expected.

5. IDEA 5 OF 8

   Deforestation can be reversed

   Ritchie explains how deforestation rates have changed and what drives them.

   In her account, in some regions forest loss has slowed or even reversed, while in others it continues. She links the main causes to farming.

6. IDEA 6 OF 8

   Food choices matter

   Ritchie discusses how food production affects land, emissions and biodiversity.

   In her account, farming takes up a large share of land and produces a large share of emissions, and it is a main driver of wildlife loss.

7. IDEA 7 OF 8

   Plastic problems have solutions

   Ritchie explains where ocean plastic comes from and how to reduce it.

   In her account, most of it enters the sea from a few countries with weak waste systems, through rivers. She says knowing the sources shows where change matters.

8. IDEA 8 OF 8

   Overfishing can be managed

   Ritchie shows how some fisheries have recovered with good management.

   In her account, when countries set catch limits and enforce them, fish populations can rebuild over time. She sees this as evidence that good rules can work.
