I'm going to present our PowerPoint on humans and ecosystems. 00:00:06
We live in ecosystems and change them. 00:00:12
Humans participate in almost all ecosystems as consumers 00:00:17
because we obtain natural resources from them. 00:00:21
Natural resources are other things we obtain from ecosystems 00:00:25
and consume to carry out activities. 00:00:30
These are renewable resources and these are non-renewable resources. 00:00:32
The intelligence of our species enables us to exploit natural resources. 00:00:43
This permits us to develop and expand, but unfortunately this is very aggressive. 00:00:50
We measure and create inequalities between countries and societies and imbalances in ecosystems. 00:00:58
We over-exploit natural resources. 00:01:20
In other words, we consume too many resources too fast. 00:01:24
We use them more quickly than they can use them when they are right. 00:01:28
leaving thousands of them to run out. 00:01:34
We occupy the orchard and produce the land. 00:01:37
Our fields of crops, pastures for livestock, 00:01:40
cities and factories support the environment. 00:01:44
The waste and fumes we produce 00:01:49
produce biotopes destroying the ecosystem. 00:01:51
This is a forest. 00:01:55
We distribute resources poorly. 00:02:01
Health-free societies consume too many resources, while some people in poor societies have almost nothing. 00:02:15
This is unfair and it produces social problems. 00:02:28
This is an element of pure societies, and this is an element of rich societies, and this is an element of poor societies, and on the background is an element of rich societies. 00:02:32
Sustainable development. If we continue to live by the current development model, it will be difficult for future generations to survive. 00:02:53
We mustn't reject the idea of development because the human beings have the right to have a clean ecosystem. 00:03:03
Sustainable development involves a rational and fair use of natural resources that is respectful of nature and guarantees the survival of future generations. 00:03:12
To protect the environment, we must follow certain rules, and in the background you can see the picture of an ecosystem. 00:03:25
Achieve a rational use of resources. 00:03:36
When suitable resources do not run out, we must use mainly renewable resources such as wood and give them to regenerate them. 00:03:39
If we do not use renewable resources, we must reduce the extractions, reduce the products manufactured from them and recycle useless materials. 00:03:51
Respect nature. 00:04:10
We must create nature reserves, protective areas in which human activity is provided, 00:04:12
In order to prevent the destruction of the ecosystem, we must also reduce the amount of waste and harmful lithiums we produce when this is there in our planet. 00:04:19
4. The survival of future generations 00:04:35
To ensure that the people of the future can enjoy the earth as we do, we think it is important that the rest of the countries take the right steps to stop wasting resources and to want to think that the earth is enough resources for everyone. 00:04:39
Here we can see the bear, the food we use, we use and we take home. 00:04:59
Vocabulary. We need to make up again. 00:05:09
Guarantees. Promises. Therefore, as a result, we generate, form up again. 00:05:17
Fumes, toxic paper, insurance, guaranty, we get refused on livestock farm. 00:05:25
Questions. 00:05:34
What are natural resources? 00:05:38
Resources that we obtain of ecosystems and we use them in our benefit. 00:05:42
How we destroy ecosystems? 00:05:52
Well, because we build cities in Poland and... 00:05:59
Why is it important how we distribute natural resources? 00:06:12
Because some people are very poor and others are rich. 00:06:19
And what do we have to do to ensure we don't run out of energy? 00:06:26
Bones sinking like stones 00:06:36
All that we fall for 00:07:20
Homes, places we've grown 00:07:23
All of us have done before 00:07:28
We live in a beautiful world 00:07:31
Yeah, we do, we do 00:07:37
We live in a beautiful world 00:07:41
Sinking like stones, all that we've fought for 00:07:50
Homes, places we've grown, all of us have done before 00:07:55
We live in a... 00:08:02
Yeah, we do, yeah, we do 00:08:07
We live in a... 00:08:13
We live in a... 00:08:20
It's a fun, it's a wonderful 00:08:38
Cause yeah, everybody here 00:09:12
It's got somebody to lean on 00:09:18
Biology, how to live and interact 00:09:20
Species and biomes 00:09:34
And the place where an organism lives 00:09:39
Habitat 00:09:42
Provides the things an organism needs 00:09:43
Organism 00:09:46
A fun species 00:09:48
Population 00:09:50
Species for things 00:09:52
More populations 00:09:54
Communities 00:09:56
Birds and flies 00:09:58
Bugs and rocks 00:10:00
Temperature and soil, they make up an ecosystem 00:10:01
Ecosystems have a flow 00:10:05
Sunlight, water, oxygen, temperature, soil 00:10:10
Yeah, so if I got into this low, oh, oh, oh 00:10:14
Space is down, it's a brown, ow, ow, ow 00:10:26
Weather, hurricanes and snow 00:10:30
That's how limiting factors make them leave their home 00:10:34
Adaptations change animals over and over 00:10:38
Alter body, physical, behavioral, behavioral 00:10:42
Eating, finding homes, niche a kind of role 00:10:46
No matter day or night, competition, species die off 00:10:50
From the ocean to the land 00:10:54
Animal killing and eating them 00:10:57
Is it a predator or is it a prey? 00:11:01
They will catch, kill their prey, it's what predations fall 00:11:05
Ego systems have a flow 00:11:10
Sunlight, water, oxygen, temperature, soil 00:11:17
Yeah, so, if I are ignore life, no 00:11:21
But there's no, oh, oh, oh, spaces down 00:11:25
It's a ground, out, out, out, weather 00:11:35
Hurricanes and snow 00:11:38
That's how limiting factors make them leave their home 00:11:41
A close relationship between two species and one benefits 00:11:45
I'll tell you that there are three types of symbiosis 00:11:57
Neutralism is the one that benefits each species 00:12:01
When one isn't hurt or harmed, it's commensalism 00:12:05
When a parasite harms our host, host, host, host 00:12:09
Parasite is on, lives inside, all outside 00:12:13
On an ego, systems have a flow 00:12:16
Sunlight, polarized, you can tell the difference 00:12:20
Yes, it's fire in your life 00:12:24
No, fire that grows like metal 00:12:27
When my soul shuts down 00:12:30
Space is down 00:12:34
When I burn 00:12:38
For rookies and snobs 00:12:42
That's how limiting factors 00:12:44
Make them leave their homes 00:12:46
