Christianity
OVERVIEW
Christianity has the largest religious following in the world, with almost 2.4 billion members and a 2,000-year history, and is expected to grow to 2.9 billion in 2050, with growth concentrated in Latin America, Africa and Asia.
Christians follow the teachings of Jesus Christ who they believe is the Son of God made man, and who died and rose again. However, there is huge variety in how the Christian faith is practised in both the key established traditions (Catholic, Orthodox, Protestant, Episcopalian) and the newer traditions of the last 150 years (Evangelical, Charismatic / Pentecostal, Independent).
Since 2015, in particular, the Laudato Si’ encyclical issued by Pope Francis, in which he called on people to ‘hear the cry of the Earth and the cry of the poor', has had a hugely positive impact on how Christians globally view and treat nature.
'To safeguard biodiversity, we can take action by planting trees and form partnerships with organisations that care for land and seas. We must act together so that there is no more biodiversity loss and prioritize restoring degraded ecosystems, including on church land. We can grow Laudato Si’ gardens, living chapels, support regenerative agriculture and agroecology practices that protect and nourish human and planetary health.'

BELIEFS & VALUES
Christian beliefs & values share much common ground with conservation.
Christians believe there is only one God but that he exists in three persons: God the Father, God the Son and God the Holy Spirit. This is the known as the Trinity. Christians believe that Jesus Christ is the Son of God made flesh, and came to Earth to show, through his death on the cross (the Crucifixion) and his Resurrection on the third day, that death could be overcome and sins forgiven.
Love: Love has always been central to Christian faith. Jesus commanded, 'Love your neighbour as yourself'. This loving relationship with others now increasingly includes all life on Earth.
Care for Creation: The Earth is seen as the generosity of God, symbolic of God’s love, and therefore caring for all of God's creation is fundamental to our relationship with God. The Season of Creation (September 1-October 4) is a special time each year when Christians spend time in prayer and action for the environment.
Integral ecology: A key concept in Pope Francis's 2015 encyclical, Laudato Si', this means that 'everything is connected' and so requires an integrated, holistic approach. Nature cannot be considered as separate from ourselves, or solely for our benefit.
Rooting out greed: Over-exploitation is seen as a sin that goes against divine wisdom. Christians should resist species extinction for human benefit because all life belongs to God.
Justice: Jesus said he was sent 'to bring the good news to the poor, to proclaim liberty to captives and to the blind new sight, to set the downtrodden free'. (Luke 4:18). Christians are called to follow him and confront injustice where they find it. Destruction of the environment impacts heavily on the poorest and most vulnerable, and damages God's creation.
Animals featured in the Bible show God’s creativity and compassion: 'How many are your works, LORD! In wisdom you made them all; the earth is full of your creatures. There is the sea, vast and spacious, teeming with creatures beyond number...” (Psalm 104:24-27). Christians have a responsibility to protect and care for nature.
The window of St Francis of Assisi, Westminster Abbey, London. St Francis (1181-1226) is the patron saint of animals and ecology, and is often depicted with birds and animals. His prayer, Canticle of the Creatures, giving praise and glory for all of God's creatures, is one of the inspirations for Laudato Si'.
DIFFERENT CHRISTIAN TRADITIONS
Christianity is very diverse and multi-faceted in terms of its traditions, denominations, practices and interpretations.
While all share common foundational beliefs, there is also huge variety in how the Christian faith is practised – both in the established traditions (Catholic, Orthodox, Protestant, Episcopalian) and in the newer traditions.
With the rise of Evangelical, Charismatic, Pentecostalist and Independent churches over the last 150 years, there are at least 45,000 different Christian traditions, according to the World Christian Encyclopedia.

CHRISTIANS AND THE ENVIRONMENT
Environmental care has become a priority at the highest levels of the key Christian traditions. In 1990, the three established traditions spoke about this. Click below to find out what they said.

POPE FRANCIS AND LAUDATO SI'
On care of our common home
In 2015, Pope Francis released a 184-page encyclical (public) letter, Laudato Si' ('Praise be to you'), addressed to 'every living person on this planet', in which he called on people to hear 'the cry of the earth and the cry of the poor'.
Subtitled 'On care of our common home', Laudato Si' challenged the world to understand that we are connected with each other, with the natural environment, and with those who will come after us, and that ecological crises are moral challenges that affect the poor and vulnerable most of all. It invited us to ask: 'What kind of world do we want to leave to those who come after us, to children who are now growing up?'
The encyclical also affirmed the 'very solid scientific consensus' that climate change is occurring and that human activity is its primary driver, and warned that efforts to reduce climate change must not be at the expense of people in poverty.
The encyclical has had a huge impact, and not just within the Catholic Church. Five years after its publication, it was the most cited Catholic text in the highest ranked and most influential journals dealing with scientific, social, economic development, and theological issues from a socio-environmental perspective.
Today, Laudato Si' remains a pivotal document in shaping how the 1.3 billion members of the Catholic Church globally respond to the environmental crisis, and inspiring many people of other faiths and none as well.
In 2023, the Pope released a follow up letter, Laudate Deum ('Praise God for all his creatures') in which he highlighted the urgent need for a more sustained response to the ecological crisis in light of the climate crisis, and strongly criticised the lack of progress in the eight years since Laudato Si'.
EXPLORE CHRISTIAN ACTION IN CONSERVATION
There are almost 2.4 billion Christians today, found in virtually all corners of the world.
Many Christian groups are taking a proactive role in protecting and conserving nature, visible through their participation in Climate Summits, endorsing sustainable agriculture systems such as ‘Farming God's Way’, and by honoring an annual season of Creationtide to celebrate nature. Christian action on the environment includes replanting degraded forests, protecting vulnerable species, caring for threatened habitats, living simply with an awareness of our lifestyle choices, greening churches and congregations, and lifting Christian voices to defend biodiversity through dialogue and action. The Catholic Church is also one of the largest divestors from fossil fuels.
