Bioterror the next big threat that we have yet to dedicate thorough time to.

Bill Gates, who already warned us about the pandemic and climate change, says bioterrorism is the next big threat we're not worrying about enough.

Bill Gates is widely known for his business acumen and humanitarian efforts. But the co-founder of Microsoft and multibillionaire philanthropist has also gained a reputation for predicting technological advancements as well as health crises and pandemics.

In a TED Talk in 2015, Gates warned that a pandemic was only a matter of when, not if, and that the world was not prepared to deal with it. Lately, his warnings have centred on another growing threat to global security: bioterrorism.

According to Interpol, bioterrorism refers to “the intentional release of biological agents or toxins for the purpose of harming or killing humans, animals or plants with the intent to intimidate or coerce a government or civilian population to further political or social objectives".

In a recent interview with the BBC, British journalist Amol Rajan asked Gates what was in his view the big future threat facing humanity that we were not thinking about enough.

Because we were starting "to think enough about climate change," Gates replied, the answer was "bioterror, which is really awful".

Bioterror and pandemics are sort of the same, says Gates, because they expose mankind to dangerous and even deadly diseases, but “bioterror is a little harder to defend against, because whoever’s trying to do it is [doing it] consciously and understands your defence system, so they can be trying to design around them”.
