자막 (46)

0:00- You may have gotten wind,

0:01the turbines like these are killing all the birds,

0:05so wind power's bad, but how accurate is that?

0:08Yes, wind turbine collisions account for somewhere

0:10between 140,000 to around 680,000 bird deaths each year.

0:15Mainly small migrating songbirds.

0:16And that's why the people who plan

0:18where wind turbines go work to study

0:20and avoid bird migration roots,

0:21sometimes even turn off wind turbines

0:23during peak migration times.

0:25Okay, that's not nothing

0:26but those wind turbine numbers pale in comparison

0:28to how many other bird deaths we are responsible for.

0:31Around 6 million birds crash into communication towers

0:34like the ones your phone's talking to you right now.

0:35These towers are tall.

0:36They shine lights in the night sky,

0:38which can disorient songbirds traveling at night.

0:40And up to 50 million birds get tangled

0:42in overhead electricity lines each year,

0:44with about 5 million getting electrocuted by 'em.

0:46About 72 million birds get poisoned each year

0:49by things like pesticides we use to protect our crops,

0:52or lead poisoning from spent ammunition,

0:54swallowed by scavenger birds feeding on carcasses.

0:56And more than a billion birds die every year

0:59from crashing into big glass buildings or household windows

1:02or other confusing glass things we keep putting everywhere.

1:04I guess it's clear, you know, what do you expect?

1:06But you know who the real killers are,?

1:08Domesticated cats.

1:10Yes, more than 3 billion birds,

1:12billion with a b,

1:14get killed by household kitties or feral cats every year.

1:17That's almost one feline bird murder

1:19for every two humans on Earth.

1:21"Not my cat," I hear you saying.

1:23And to that I say, "Yes."

1:24Even your cat.

1:26Cute, but also deadly murder machines.

1:29Anything that kills wild birds is not good.

1:30But it seems like if you want to save the most birds,

1:33maybe we should be talking about cats instead.

1:35Don't ask me though, I'm a dog guy.

1:37Follow me for more cool science videos.
