Types of environmental impacts, their effects, and what we can do about them

ENVIRONMENT

The global environment is now facing unprecedented crises such as global warming, extreme weather, and biodiversity loss.
At the root of these problems is the “environmental burden” caused by our human activities.

This article will explain the types of environmental impacts, their specific effects, and what each of us can do to help.

History and Current State of Environmental Burden

Since the Industrial Revolution, mankind has built a mass-production, mass-consumption, mass-disposal type society.
Soot and fumes from factories, automobile exhaust, and chemical runoff have increased along with economic development.

In the 1950s and 1960s, Japan experienced serious pollution problems.
Minamata disease, Yokkaichi asthma, Itai-itai disease, and other environmental pollution brought about by industrialization caused many health problems.

Today, environmental burden is a serious problem on a global scale.
Our daily lives and economic activities are placing a burden on the environment in various ways, such as abnormal weather and sea level rise due to global warming, health hazards caused by air and water pollution, waste problems, and loss of biodiversity.

Types and Impacts of Environmental Impacts

Environmental impacts can be broadly categorized into the following types, each of which has serious effects.

1. Global warming

気球異常気象

Emissions of carbon dioxide and other greenhouse gases are increasing the average global temperature.
The resulting effects include melting glaciers, rising sea levels, and more frequent extreme weather events.

Typhoon No. 21 in 2018 recorded a maximum instantaneous wind speed of 58.1 m/s in Osaka Bay, flooding Kansai International Airport and damaging many houses.
The intensification of abnormal weather in recent years is believed to be the result of global warming.

2. Air Pollution

地球大気汚染

Nitrogen oxides and sulfur oxides emitted from factories and automobiles contribute to air pollution; particles as small as 2.5 micrometers in diameter, such as PM2.5 (fine particulate matter), are known to increase the risk of asthma and lung cancer.

Air pollution is a serious problem in China’s large cities due to rapid industrialization.
In January 2013, Beijing recorded a “dangerous” level of PM2.5 concentrations exceeding 900 μg/m³.

3. Water Pollution

水質汚染

Factory effluent, domestic wastewater, and pesticide runoff cause water pollution in rivers and oceans. Eutrophication caused by organic matter generates “red tides” and “blue tides” that lead to abnormal proliferation of plankton, resulting in mass mortality of fish and shellfish.

In Bangladesh, wastewater from leather factories has seriously polluted rivers near the capital city of Dhaka. High concentrations of chromium and other heavy metals have been detected, and there are concerns about the health hazards to nearby residents.

4. Soil pollution

タールによる土壌汚染

Illegal dumping of toxic substances and excessive use of pesticides cause soil contamination. Soil contamination by heavy metals such as cadmium and lead contaminate crops and threaten food safety.

In the Jinzu River basin in Toyama Prefecture, Japan, there used to be many cases of “itai-itai disease” caused by cadmium contamination. Many residents suffered from osteomalacia due to cadmium contamination of soil and rivers.

5. Loss of biodiversity

生物の多様性

The destruction of the natural environment due to development and pollution has deprived habitats for many living organisms, threatening them with extinction.
Our survival depends on a wide variety of ecosystem services, and the loss of biodiversity is shaking the foundations of these services.

According to the World Wildlife Fund’s (WWF) Living Planet Report 2020, vertebrate populations have declined by an average of 68% over the past 50 years.

6. WASTE PROBLEMS

海洋廃棄プラスチック

Our mass-consuming society produces enormous amounts of waste.
Plastic waste is one of the main causes of marine pollution. Marine life can accidentally ingest plastic, leading to health problems and death.

Some predict that by 2050, the amount of plastic in the ocean will exceed the amount of fish.
Marine plastic pollution can have long-term effects on ecosystems and human health.

Efforts to Reduce Environmental Impact

Efforts by the International Community

The United Nations has set “Responsibility to Create Responsibility to Produce” as one of the Sustainable Development Goals (SDGs), aiming to ensure sustainable production and consumption patterns.

The Paris Agreement, adopted in 2015, aims to pursue efforts to keep the global average temperature increase well below 2°C above pre-industrial levels and limit it to 1.5°C.

National and Local Government Initiatives

Japan has declared itself “carbon neutral by 2050” to achieve virtually zero greenhouse gas emissions by 2050. Efforts include expanding the introduction of renewable energy and promoting the use of electric vehicles.

The Tokyo Metropolitan Government introduced a cap-and-trade system in 2010 that requires large business establishments to reduce their CO2 emissions.
This system has successfully reduced CO2 emissions by 27% at eligible business sites by 2019.

Corporate Initiatives

Toyota Motor Corporation has announced its goal of 100% electric vehicles in new car sales globally by 2050.
Nissan, Honda, Suzuki, and others are also focusing on expanding sales of electric vehicles.

Education and Citizenship

The Ministry of the Environment provides opportunities for children to engage in proactive environmental activities in their communities through the “Children’s Eco-Club.” By 2020, approximately 250,000 children nationwide had participated in the program.

Environmental NPOs in various regions are engaged in a variety of activities such as beach cleanups, forest conservation, and environmental education.
These grassroots activities play a major role in raising environmental awareness.

What each of us can do

Each of us has an important role to play in reducing our environmental impact. Below are three actions you can start taking today. 1.

Reduce electricity consumption by frequently unplugging unused devices when you leave a room or when you are not using them. 2. Reduce plastic waste by using your own bags or eco-bags instead of plastic bags. 3. Reduce food leftovers Food loss amounts to about 1.3 billion tons per year worldwide. Reduce food leftovers by being careful not to overbuy or overcook food.

Use eco-bags! Use eco-bags

There are many other things we can do, such as saving water, using public transportation, and choosing environmentally friendly products.
Each person’s small action has the power to make a big difference.
