Human Impact in ecosystems and biodiversity
Natural resources include goods and services
Exhaustible resources will eventually run out no matter how slow you use them, They are non sustainable resources. Example: coal and metals
Inexhaustible resources will never run out no matter how fast you use the,. They are sustainable. Example: sun, wind
Sustainability: to use a resource in a sustainable way= to usea resource so that it can always regenerate and perform its ecosystem services
Renewable resources depend on how you use them. I you use them slowly enough to allow them to renew, you can use them indefinitely. You will e using them in a sustainable way. If you use them faster than they can renew themselves, they will eventually run our
Ecological footprint: Each person or human population has a n ecological footprint: the amount of natural resources they use or degrade
Biocapacity: the ability of its proactive ecosystems to regenerate the ewneable resources used by a population city, region, country, or the world
In 2012, the world's ecological footprint was 50% higher than the planet's estimates logn=tem biocapacity
Major socio economic causes of todays envriornmenral problems are:
Population growth
Wastegul and unsustainable resources
Poverty
Omission of the harmful environmental health costs of goods and services in market prices
-Increasing isolation from nature
Competing environmental worldviews
The human population has grown exponentially to the current population of 7.8 billion people. By 2050 population could reach 9.8 billion. No one know how many people earth can suppoert, However, our large and expandind ecological footrpints and the resulting of widesrpread natural capital degration are disturbing warning sgins that we are nearin a limit and something needs to change
The most developed 17% of the world's population use out 70% of the earth's natural resources
However, affluence in a society can begin to allow for: widespread and better education about environmental issues
More money available for developing technologies to reduce pollution, environmental degradation, and resource waste
Poverty is a condition in which people lack enough money to fulfill their basic needs for food, water, shelter, health care, and education
Companies proving goods for consumers generally are not required to pay for most of the harmful environmental and health costs of supplying ushc goods. For example: timber companies of not pay for the consequences of air pollution such as land lost to rising sea levels or worsening hurricanes, or soil degraded by acid rain
Half of the world's population is urban, many billion do not full appreciate the beauty and complexity of nature. M
Many people don't understand their impact, or simply don't care. People have differentt priorities when it come to the environment- some put personal wealth above environmental well-being . Som people are not concerned with long term effects that won't affect them because they will be long dead.
Ecological racism/orejudice
Some socioeconomic groups are more affected by environmental degradation and disasters than others. People who have enough money to protect themselves from environmental degradation and disasters would in theory have less incentive to protect the environment
Tagedy of commons is an economic theory: Evereyne with access to a shared resource uses it in a uncontrolled, self-interest manner, eventually exhausting to degrading it to the point the no one can benefit from it all
Both poor and the rich are destroying the environment
Specific types of natural capital degradation and the main activities that cause them
