destruction of natural ecosystems is one of the biggest threats to our planet, whether through climate change, natural events or human interference way are losing vital habitats.

否定副詞倒裝句型

Areas like forests or coral reefs not only harbor millions of species, but they provide valuable ecosystem service's benefits as humans gain from nature.

Thankfully, people across the planet are working to restore.

In some instances, fire is as important to a forest as water and the sun.

It can release valuable nutrients, clearing space for light, stimulating new growth.

But in areas like the American Northwest, increasingly warmer and drier climates a changing how and if forests can recover this fire.

You can just see what the burn looks like after it goes through and how there's just nothing left.

Fires go through, and the tops of these crowns would have all kinds of cones ready to open up and drop seeds.

Because these fires are so large and massive due to increased temperatures from climate change, there's just nothing left here.

Gran Canary runs drone seed and hopes the tech startup from Seattle can make a difference on the mission of our company is to make reforestation scalable for the purpose of making a dent in carbon emissions.

Utilizing drone swarms Drain Seed surveys the land using three D laser scanning technology known as lied.

This gives them a huge number of data points, which they used to build a detailed map of the area.

We run software to then identify the obstacles off of that three d terrain map way actually get a point cloud of about 800,000 points per second, most like lighter and self driving cars around 200,000 points per second.

We were able to identify these micro sites where seed vessels will grow really well.

Software then plans out all of the missions for the aircraft.

If you were, like planning out, like how to mow your lawn.

It's a lawnmower pattern that goes back and forth in different areas.

The operator controls takeoff and landing, wants the drone's airborne Aye, aye, takes over to fly the predetermined route way.

Each one of those has somewhere between 4 to 6 seeds in it.

Human planter can do about two acres a day.

Maybe three drones were targeting 20 to 40 depending upon the terrain, according to Canary.

It can take two years to grow trees in a nursery, which is time these forests just don't have.

If these areas are left without having trees planted immediately after a fire, invasive species quickly move in, changing the landscape and making growth of trees much harder.

The big risk is, is this gonna transform and turn into step or Savannah?

And it's gonna come back as 10 foot tall shrubs.

As far as like mitigating the worst effects of climate change, there's really a handful of things you could d'oh!

The best one is planting trees because they're the most efficient thing you could do to sequester carbon justice.

Forests of vital ecosystems on land, So a coral reefs in the ocean.

Despite making up less than no 0.1% of the ocean, they protect land from storms and waves on provide valuable resource is such as the fish we eat but research in decline.

Thanks to overfishing and climate change, Half of all reef systems have already being destroyed, scientists predict.

At in the next 30 years, if we not do any things more than 95% off the coral reefs around the world, we'll be in dangers.

On a small island 140 kilometres from Bangkok, a team of biologists working on ways to restore coral reefs damaged by global warming, the ocean absorbs much of the heat trapped by greenhouse gases.

Since 1993 the rate of ocean warming has more than doubled.

The highest temperature that we got was 34 center greats, and that makes many quarrels in tyrant bridge and eventually die.

When stressed by conditions such as temperature change, Carl's expel the symbiotic algae that gives them their distinctive colors, a process known as bleaching.

The algae lives inside the coral for protection and in return uses photosynthesis to help feed the coral.

If a coral is severely bleached, the chances of disease and death increase.

The important thing that we have to make sure is that the baby corrida be pretty.

They have to be able to withstand to the changes off environments Professor Challenge.

His work is centered on growing resilient coral.

One way, she believes, is to improve the corals.

Genetics Challenge and her team have developed artificial fertilization techniques on a mass scale during the spawning season between January and March, they collect eggs and sperm from several coral colonies and bring them up on land to fertilize in their hatchery.

Here, the larvae have grown on concrete plates in tubs full of seawater.

They're kept in the hatchery for two years, so they're strong enough and then re planted by hand on the sea floor.

They have high diversity off genetics, and these can help them to so live in the changes environments.

Funding issues mean the hatchery doesn't have reliable air conditioning, running water or perfect lab conditions.

But in a twist of fate, crude facilities might just have helped the baby corals.

So usually the temperature of the water in hatchery is higher than normal.

Well, who actually is like a one star hotel resting the coral in this one star hotel actually make over baby baby coral stronger and can we stand to real temperature when we release them back to the oceans theme have grown about 10,000 corals so far.

Corals with this genetic diversity have a survival rate of at least 50% while the natural survival rate is just no point no 1%.

But the success comes at a cost $100 for each call replanted.

In recent years, mass coral bleaching events have happened all over the world, from Hawaii to Australia, the Gulf of Mexico, Madagascar and the more games.

But projects like this in Thailand show there's hope for our delicate ecosystems.

So to see more fish, more animals like crab trim za coming to the areas using over coral's as the habitats as a home.

 So far in 2019 weather and climate events killed more than 4000 people globally and caused around $42 billion in insured losses.
