Antibiotics revolutionized medicine, but their effectiveness is threatened by resistance. This new page presents global data and research on antibiotics and antibiotic resistance.<br><br><a href="https://ourworldindata.org/antibiotics" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/0983df2b-3d7f-416f-71be-f4ad93a8a100/w=1350"/></a>

Many countries refuse to share their data, which is a risk for antimicrobial resistance.<br><br><a href="https://ourworldindata.org/antibiotics-livestock-data" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/f76ef941-7b32-4c9f-4fcf-c6a07067ff00/w=1350"/></a>

Overuse is a risk for antibiotic resistance, but there are ways to reduce it.<br><br><a href="https://ourworldindata.org/antibiotics-livestock" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/f40ec941-5824-4d88-c91d-6012bd888e00/w=1350"/></a>

In some countries, most children and pregnant women are anemic. There are low-cost ways to tackle this.<br><br><a href="https://ourworldindata.org/billions-people-suffer-anemia-cheap-ways-reduce" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/90ee4eca-4e37-483d-f622-966a7db3fc00/w=1350"/></a>

Adapting planting dates, selecting better crop varieties, and increasing access to irrigation and fertilizers could offset potential declines in crop yields.<br><br><a href="https://ourworldindata.org/climate-change-will-affect-food-production-things-can-adapt" target="_blank"><img src="https://ourworldindata.org/images/published/climate-agriculture-adaptation-featured.png"/></a>

Maize yields could see significant declines, but wheat could increase. Impacts across the world will be very different.<br><br><a href="https://ourworldindata.org/will-climate-change-affect-crop-yields-future" target="_blank"><img src="https://ourworldindata.org/images/published/climate-agriculture-featured-2.png"/></a>

Cancer is one of the biggest health challenges worldwide. Around 15% of all deaths are caused by cancer, making it one of the most common causes of death globally.<br><br><a href="https://ourworldindata.org/cancer" target="_blank"><img src="https://ourworldindata.org/images/published/cancer-thumbnail.png"/></a>

Climate change has slowed the productivity of key crops such as maize and soybeans, but might have had small positive impacts on wheat.<br><br><a href="https://ourworldindata.org/crop-yields-climate-impact" target="_blank"><img src="https://ourworldindata.org/images/published/climate-agriculture-1-thumbnail-v2.png"/></a>
